Invoices Stuck with Requestor in Account Coding

Hi,

Over the past few months, we've received multiple reports indicating that after completing account coding on invoices, users continue to receive account coding notifications. These invoices remain in a "Needs Revalidation" status, preventing requestors from taking further action. Consequently, Accounts Payable (AP) must manually withdraw the invoice from the account coding workflow and validate it to allow progression through the approval workflow. It's random but not happening frequently. Can anyone please provide insights on why this is happening? Thank you!

Regards,

Nikhita.
